Pengaruh Penambahan EM4 dan Molase Terhadap Pertumbuhan dan Efisiensi Pakan Larva Black Soldier Fly

Abstract

Pengelolaan sampah yang modern dan tepat guna dapat meningkatkan waktu penguraian sampah yang dihasilkan oleh pasar tradisional. Penelitian ini bertujuan untuk memanipulasi karakteristik larva dengan pakan sampah organik pasar tradisional dengan pemberian feeding rate 80%. Nilai waste reduction index (WRI) dalam penelitian antara 5,23 %/hari - 5,25 %/hari. Nilai Feed Conversion Ratio (FCR) dalam penelitian berkisar antara 9,95%- 10,40%. Persentase efficiency of conversion of digested Feed (ECD) penelitian bernilai antara 10,17%-10,68%, serta tingkat kelangsungan hidup larva berkisar 81%-92%. Hasil pengamatan melalui uji ANOVA dan DMRT mendapatkan bahwa pemberian EM4 dan molase berbeda nyata(a>5%) pada pertumbuhan bobot dan panjang larva BSF. Berat akhir larva BSF perlakuan 1 sebesar 11,55 gram, perlakuan 2 sebesar 12,99 gram, perlakuan 3 14,69 sebesar gram, dan perlakuan 4 sebesar 15,46 gram. Panjang akhir larva BSF perlakuan 1 sebesar 16,67 mm , perlakuan 2 sebesar 18,10 mm, perlakuan 3 sebesar 20,13 mm, dan perlakuan 4 sebesar 19,27 mm. Pertumbuhan larva terkecil terdapat pada perlakuan kontrol dan penambahan EM4, sedangkan penambahan molase dan kombinasi kedua mendapatkan pertumbuhan larva yang terbaik.

Modern and appropriate waste management can accelerate the decomposition time of waste generated by traditional markets. This study aims to characterize larvae fed with organic waste from traditional markets and feeding rate 80% treatments. The percentage waste reduction index (WRI) values ranged between 5.23 %/day-5.25%/day. The feed conversion ratio (FCR) values ranged from 9.95%-10.40%. The efficiency of conversion of digested Feed (ECD) percentages varied from 10.17%-10.68%, while the survival rates (SR) percentage ranged between 81%-92%. The observations through ANOVA and DMRT tests revealed that the addition of EM4 and molasses showed a significant difference (a > 5%) in the growth of weight and length of BSF larvae. The final weight of BSF larvae in treatment 1 was 11.55 grams, treatment 2 was 12.99 grams, treatment 3 was 14.69 grams, and treatment 4 was 15.46 grams. The final length of BSF larvae in treatment 1 was 16.67 mm, treatment 2 was 18.10 mm, treatment 3 was 20.13 mm, and treatment 4 was 19.27 mm. The smallest larval growth was observed in the control treatment and with the addition of EM4, whereas the addition of molasses and the combination of both achieved the best larval growth. The lowest larval growth occurred in the control and EM4 treatments, while the addition of molasses and its combination with EM4 resulted in the best larval growth.
